The forward, who finished last season on the books at Bradford City, started his career with his boyhood club Preston North End, breaking into the Lilywhites side as they unsuccessfully fought against relegation from the Sky Bet Championship during the 2010/11 campaign.
Having signed for Premier League side Swansea City in August 2012, he was on the move again the following January as he joined Crawley Town after a brief loan spell with Shrewsbury Town.
Moving on to Fleetwood Town in June 2014, Proctor spent the second half of last season with Parkinson at Bradford City, starting 15 matches and scoring six goals including one on his debut and one in the Bantams’ play-off semi-final defeat to Millwall.
Marking his noncompetitive debut for Wanderers by netting a late winner against FC Helsingor in pre-season, he came of the bench to make his maiden senior appearance for the club on the opening day of the season against Sheffield United.
Proctor was handed his first start in the Whites' next outing against Blackpool, opening the scoring just before half-time as Bolton suffered an early EFL Cup exit.
